SPECIFICATION forming part of Letters Patent No. 782,578, dated February14, 1905.

Application filed September 3, 1904. Serial No. 223,268. i

T0 all whom t vta/y concern,.-

Be it known that I, THOMAS PADGETT, a citizen of the United States ofAmerica, residing at East Palestine, in the county of Columbiana andState of Ohio, have invented certain new and useful Improvements inWindow-Locks,

of which the following is a specication, reference being had therein tothe accompanying drawings.

This invention has relation to window-locks, and has for its object theprovision of novel means whereby the two sashes of a windowframe may belocked in any position desired.

Another object of this invention is to provide a window-lock whichmay bereadily constructed in the frame of awindow, whereby the 4frame Will notbe disgured and the lock may be easily and quickly manipulated at anytime it be desired.

Briefly described,` my invention contemplates employing a lock whichwill engage either one of the sashes when they are in a raised orlowered position, and I provide a recess in the one side of the frameadjacent to the meeting-rails of the sashes, and in said recess I mountmy improved lock. The lock is of a friction nature and is adapted toengage each sash, and I provide two grippinglevers which are actuatedYby a cam mounted in said recess, and I provide novelmeans for rotating'said cam.

The above construction will be hereinafter more fully described andthenl speciiicall y pointed out in the claims, and, referring to theparts throughout the several views, in which-g Figure 1 is atransversesectional view of one side of a window-frame having two sashesmounted therein. Fig. 2 is a side elevation of a portion of awindow-frame, showing the sashes removed and the gripping-levers in planview. Fig. 3 is a top plan viewof a cam employed in connection with myimproved window-lock. Fig. I is a detail perspective view of one of the`gripping-levers'. Fig. 5 is a plan view of a shaft or pinused inconnection with the cam-gripping levers. Fig. 6 is a detail perspectiveView of a cam. Fig. 7 is a detail perspective view of another grippingling-yoke 27, which is secured, as indicated at IOO lever, and Figs. 8and 9 are detail views of a modified view of gripping-levers which maybe made of two sections.

To put my invention into practice, I have provided a recess l in theside frame 2 of the window, and adjustably mounted within the side frame2 andwithin the recess 1 thereof arethe sashes 3 and 4, these sashesbeing separated'by a weather-strip 5, which is mounted vertically withinthe frame between said sashes. When the sashes have been mounted withinthe frame, a side strip. 6 is secured to the frame 2, which will partlyclose the recess 1 formed within the` side frame. Upon the rear face 7of the recess is mounted a gripping-lever 8, the ends of which are bentat right angles, as'indicated at 9 and-9', and in the body portion ofthe gripping-lever I,provide two slots 10 and 11. The gripping-lever isslidably mounted upon the rear face of the recess by a screw 12, whichpasses through the slot 11 and permitsof a sliding movement. In the rearface of the recess is also mounted an escutcheon plate or socket 14, andin said socket is rotatably mounted a shaft or pin 15. This shaft or pinis provided intermediate its length and upon its one end with a squareportion 16, and said pin or shaft protrudes through an opening 17,formed in the side strip 6, and upon the square end of said shaft isremovably mounted a crank-lever 18, carrying a handle 19. The shaftprotrudes through the slot 1() of thegripping-lever and has mounted onits intermediate square portion a cam, which is illustrated clearly inFig.

the -shaft 15 is mounted another gripping-lever, 23, which has its endsbent` at right an- 9 gles, as indicated at 24 and 25,`and the bodyportion of this gripping-lever is provided with a slot 26. To retain thecam 2O and the gripping-lever 23 in position, I employ a retain- 28, tothe rear face 7 of the recess 1. The reference-numeral 29 indicates apin which is carried by the gripping-lever 23, and the object of thispin will be hereinafter more fully described. Y

The operation of my improved lock and the manner of securing the sashesin any desired position within the frame is as follows: To lock eitherone of the sashes in a closed position or in a raised or loweredposition, the crank-lever 18 is slightly rotated to impart a similarmovement to the shaft 15, and when said shaft revolves it rotates thecam 20, and the cam portion 21 will engage the end 9 of thegripping-lever 8 and move the same until the end 9 of said lever hasengaged the frame of the sash 3, and the cam 21 will engage the end 25to force the gripping lever 23 inwardly into engagement with the frameof the sash 4, and by the particular formation of the cam-surface thesashes will be held in a locked position/whether raised or lowered. Tounlock the sashes of the window and return the gripping-levers to theirnormalA position, the operation is as follows: When the shaft is re-Versely rotated, the cam 21 will engage the pin 29 of the gripping-leverand release the end 9 from engagement with the frame of the sash 3, andthe cam 22 will engage the end 24 of the gripping-lever 23 and force thesame outwardly to disengage the end 25 from the frame 4.

rIhe gripping-lever, as shown in Figs. 8 and 9 of the drawings, may bemade of two sections, and any suitable fastening means may be employedfor securing said sections together; but preferably I provide onesection with pins formed integral with the section, these pins beingadapted to fit in apertures formed in the opposite section for thepurpose of fastening the sections together. It will be seen that bymaking the gripping-levers in two sections a further advantage isobtained by reason of the sections being adjusted to fit various sizesof windows, as the case may be.

It will thus be observed from the construction of my improved lock thatit is an eX- tremely simple operation to lock either one of the sashesin any position desired, and I do not care to limit myself to thespecific construction of the lock, but may change the r shape of thecams and the arrangement of the gripping-levers and said cams withoutdeparting from the spirit and scope ofthe invention.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In a device of the character described the combination with awindow-frame having two sashes mounted therein, said frame having arecess at one side, of a gripping-lever arranged in said recess andhaving an outwardly-extending end adapted to engage one sash, and itsopposite end outwardly extended and carrying a pin adjacent to thelast-named end, a second gripping-lever arranged in said recess andhaving laterally-extending ends one of which is adapted to engage theother of said sashes, a cam arranged between said gripping members andprovided with three outwardlyextending portions, one of said portionsbeing adapted to engage the laterally-extending end of the first-namedlever and the said pin, the other two of said portions being adapted toalternately engage the two laterally-extending portions of the second-named lever, a shaft on which said cam is mounted and a crank-levermounted on said shaft.

2. In a device of the character described, the combination with awindow-frame having a recess at one side, and two sashes mounted in saidwindow-frame and extending into said recess, of a sliding lever formedof two relatively adjustable sections arranged in the recess and havingboth ends bent outwardly at right angles, one of said ends being locatedadjacent to one of said sashes, the other of said ends being spacedapart from the other of the sashes, a pin carried by said lever, asecond sliding lever arranged in said recess to one side of one of thesashes, said second lever having two inwardly-bent ends, a cam arrangedbetween said levers, a shaft passing through said levers and vthroughsaid cam, said cam being fast on said shaft, and said cam heing adaptedto simultaneously move both saidlevers in opposite directions to causethem to be engaged with or disengaged from the said sashes.

In testimony whereof I afiiX my signature in the presence of twowitnesses.

THOMAS PADGETT.
